feat(telemetry): deploy-failure, S&F activity, script-run and DCL-transition instruments (ScadaBridge#81)

Adds four instruments on the already-allow-listed ZB.MOM.WW.ScadaBridge meter:
scadabridge.deployments.failed{reason}, scadabridge.store_and_forward.activity{action,category},
scadabridge.site.script.runs{outcome} + scadabridge.site.script.duration{outcome} (ms),
scadabridge.site.data_connections.transitions{state}. Queue depth, DCL connection state and
deploy-applied already existed. No new Meter, so ZbTelemetryOptions.Meters needs no change.
